Muck and the team manage to restore and uncover a picture of a dragon on the school wall. Spud and Scrambler finally return and on seeing the restored dragon picture on the wall, they follow the direction of the dragon's tongue to a loose brick, another red box and another clue. This time it's a trapezoid on the end of a line; but what does it mean? Scoop's Big Job - Following the latest clue - a trapezoid with a line extending from it Spud and Scrambler start their search at Fixham lighthouse.
